3-3-1 Analysis of a Material and Thermal Balance of the Pyrolysis of Biomass

Abstract

Judging from the common sense of today, it seems difficult to define the chemical reaction formula of the pyrolysis of biomass since biomass is a mixture of cellulose, lignin, etc. We think of an idea that a unit compositional formula ”CH_mO_n” can be used as a substitute molecular formula of biomass, where suffix ”m” and ”n” indicate the atomic ratio H/C and O/C determined by ultimate analysis. The substitute molecular formula of char and tar are also defined as CH_jO_k and CH_hO_i by a similar manner. We expressed the reaction formula of the pyrolysis of Mizunara oak using CH_mO_n, CH_jO_k and CH_hO_i, verified the thermal balance of pyrolysis, and estimated its heat of reaction.
